I would like something on cable, maybe 10-12 episodes per season, and keep it cinematic like Battlestar Galactica or The Walking Dead or Dexter. Those three shows were shot so beautifully, you forgot it wasn't a movie. 10-12 episodes per year make it more clean and tight writing-wise, and it can focus on season-long arcs. Get a cheap cast and boom, you've got your Batman series. Do 3 or 4 seasons, giving us a total of almost 50 episodes over 4 years, and everybody moves on.
